Specificationof Letters Patent. Application sied March 29, 1913.

To all whom may concern f Be it known that I, CHARLES R. LAMBERT, acitizen of the United States .of America, residing at Detroit, in thecounty oflllleyne and State of Michigan, have invented certain new anduseful Improvements in Burners, ot' which the following is aspecificationfreference beingv had therein to the accompanying drawings.

The invention relates to burners ofthe type employed in torches andplumbers furnaces, and has amongl the objects'thereof to provide aconstruction of burner in which the hydrocarbon fuel not only will beeffectively vaporized but will also be filtered, thereby removingtherefrom free carbon; further to produce a simple construction that maybe easily and cheaply manufactured.

@ther objects of the invention Will more fully hereinafter appear. y

The invention resides inlthelpeculiar construction, arrangement andcombination of parte es herein described and es particularly pointed outin the claims.

In the drawings: Figure 1 is a longitudinal section through a burnerembodying my inventionrfligf Q is en end elevation with certainpartsiremoved; and Fig. 3 is e freg ,menta/ry section. of/the structureshown in Fi/glflhin ythe 'plane of the line y-g/ of designates the bodyof the burner, preferably formed of y:1n-'integral casting provided witha .largechamber B to receive the 4and vaporizing cham ber C ofconsideraliily less sise. The chamber C is closed at its outer end andhas the inner end provided with internal threads for engaging theexternally threaded end E of the outlet conduit F. The latter has unextension G terminating-in an atomizing nozzle H extending laterallytherefrom and 'positioned to discharge into the chamber B, which is openended, but the opening I into which the nozzle ll discharges is somewhatrestricted in size. .Also the Walls of the llame-receiving or combustionchamber are provided with a plurality of apertures J, establishingcommunication bctween the interior oi the chamber B and the atmosphere.

end of the member K, the latter is cut away o'r beveled as indicated atP.

Q is a needle valve controlling the bore or passage in the `outletconduit that leadsV to the atom'izing nozzle H, and R is en operatinghandle torthe valve Q..

S is the fuel supply conduit, which is at -tached to a bore orcompartment T, and Uv is a passage connecting the comjjiartment '.l withthe chamber While any suitable type of atomizing nozzle might beemployed, l desire to use the novel structure shown in the drawings.Thus the nozzle H is formed by a hollow .nut X provided with a bore Y,and having a restricted discharge opening C extendmg through the frontWall thereof. I

In the operation of the device so fer dcscribed, the hydrocarbon fuelpasses from the ,supply through the conduit S' into the compartment Tand from the latter into the chamber C by- Way ofthe passage U. The fuelthen travels longitudinlly of the chamber C to the outer end thereof.The `\heat of the flame in the chamber B will cause the walls-ot' thechamber C to become suliciently heatedv so that the fuel passing throughthe chamber C will vaporize. F rom the outer end of the chamber C thevaporized fuel passes tl'irough the extension K and the outlet conduit Fto the nozzle H, and discharges from this nozzle by vvayfo therestricted passage C to the combustion chamber B.

Upon the vaporizing of the hydrocarbon fuel, more or less free carbon isformed and these free particles of carbon tend to ,collect atl and closethe restricted passages o'l 'the burner, particularly the opening (Y undthe opening controlled by the member Q. In order to eliminate thisobjection, l'. arrange in the vaporizinp; chamber a l'ilter throughwhich the vuporized fuel must pass before it enters the member K. Thisfilter may be of various materials, it being illustrated in the nozzle.Thearrangement of the filter Dit is preferablyxsuch that it may beremoved, the construction in the drawing allowing the filter to bedetached upon the Withdrawal of the member Also the ltel; A may beremoved -from the nozzle.

MVVhile I have shown and described one form of' my device there arevarious changes which 'might be made without departin from the scope ofmy invention. y

What I claim as, my invention is:

1.
